These devices, supplied in a plastic case with terminal block, are used for food, with a voltage stabilized and leveled at 12Vdc, inductive, capacitive, photoelectric cell transforming the output signal of the same in a changeover contact 5A at 240V of a relay in this device.
Are provided in the model ALNC (for NPN / PNP / NAMUR sensors), ALN2 in the model (for two NAMUR sensors) and in the model ALTP programmable delay on energization or de-energization (for NPN / PNP / NAMUR sensors).
